Our holographic qubit threads model also has a close connection to the so-called kinematic space [1]}. Kinematic space is an example of the application of quantum information theory to the holographic duality [2]}, [3]}. Briefly speaking, it is a dual space wherein each point is one-to-one mapped from a pair of points on the boundary of the original geometry. [2]}, [3]} proposed that in the framework of the holographic principle, the metric of a kinematic space (i.e., its spatial volume density) is defined by the conditional mutual information (CMI),
\( {D} g \equiv {d^2}{V_{{\rm {kin}}}} = {\rm {CMI}},\)
